Remy noticed that after oiling his skateboard wheels, it was easier to reach the speeds he needed to perform tricks. How did the

Sidana [21]

Answer:

The oil reduced friction between the moving parts of the skateboard. ( A )

Explanation:

The oil reduced Friction between the moving parts of the skateboard and this is because the reduction in friction between moving parts causes an increase in speed.

Remy will oil the moving parts that connects the wheels of the skateboard to the Board, because this is where the most friction is found. the friction between the wheels and the ground cannot be affected by oiling the wheels

The recommendation to segregate FLTs and the workers are as follows:-1)Reputation of warehouse:- To be in the market the reputation of warehouse should be good,it can only happen when the worker of that warehouse is happy with the management looks after worker external and internal affairs. There should be two pathways one for vehicle and other for walking in which both can’t use vice versa.2)High Profitability:- When there is no incident or accident happens between the FLTs and the workers in the warehouse then off course the worker will be regular at work then there will be high profit .3)Insurance premium:- If there is zero accident happens in the ware house then there will no claim, the company will be in the profit..

A room is filled with saturated moist air at 25°C and a total pressure of 100 kPa. If the mass of dry air in the room is 100 kg,

ANTONII [103]

Answer:the mass of water vapor is=d. 2.04 kg

Explanation:

The humidity ratio by mass is given as

x = mw / ma (1)

where

mw = mass of water vapor

ma = mass of dry air

And also humidity ratio by pressure by Ideal Gas Law is given as

x = 0.62198 pw / (pa - pw) (2)

where

pw = partial pressure of water vapor in moist air

pa = atmospheric pressure of moist air

Equating both equation we have that

Humidity ratio = 0.62198 pw / (pa - pw)= mw / ma (3)

From the from the water table at 25°C,

water vapor partial pressure = 23.8 torr

1 atm =760 torr.

1 atm = 101.325 kPa,

So, 760 torr =101.325 kPa,

Therefore 23.8 torr =3.173kPa

Humidity ratio = 0.62198 pw / (pa - pw)= mw / ma

0.62198 x 3.173 / (100-3.173)= mw / 100

1.9736 /96.827=mw/100

0.0204=mw/100

mw=2.04kg

A 10-kg block A is released from rest 2 m above the 5-kg plate P, which can slide freely along the smooth vertical guides BC and

Liono4ka [1.6K]

Answer:

Check the explanation

Explanation:

<u>Given data </u>

Mass of the block A is Ma = 10kg

Mass of the plate is Mp = 5kg

Coefficient of restitution between the block and that of the plate is e=0.75

Unstretched length of the spring is 0.6m

From the conservation of energy, we have four motion of block A from (1) to (2)

$(Ta)_1 + (Va)_1 = (Ta)_2 + (Va)_2$

Then accordingly, we will have the step by step calculation in the attached image below .
